Specification of Letters Patent.

To aZZ whom it may concern.-

Be it known that I, DIo LEWIS, a citizen of the United States, residing at Prescott, in the county of Nevada and State of Arkansas, have invented new and useful Improvements in Heaters, of which the following is a specification.

My invention is a heater, and is designed, primarily, as a water-heater for bathing and wash tubs.

In the accompanying drawings, Figure 1 is an elevation of my invention. Fig. 2 is a vertical sectional View of Fig. 1 through its center.

My invention is described as follows:

The numeral 1 represents the stove. The top of the stove is open from the pipe 4 inwardly. Extending up from the outer face of the stove are three or more arms 8, between which and on top of the stove rest the heater and boiler.

The heater consists of a heat-pipe 4, open at its lower and upper ends. Its upper end is provided with a perforated cap 5, the rim 6 of which fits on the inside of the pipe, while the flanges 7 extend, out a little way over the boiler. This cap 5 has secured in its center a smaller draft-pipe 8, which extends downwardly in the center of the heat-pipe 4nearly to the lower end of said pipe. Secured to the lower end of said last-mentioned pipe 8 are the upper ends of two or more arms 9, and to the lower ends of these arms is horizontally secured a plate 10.

Surrounding the heat-pipe 4 is the wall 11 of the water-tank, closed at its upper and lower ends. Its upper end is provided with one or more manholes 12, closed by lids 13. The purpose of these manholes is to allow for the cleaning out of the water-tank. One of these manholes might be suflicient, but in large tanks it is better to have two. Leading from the upper end of said water-tank is a steam-pipe 14. The upper end of the said pipe turns inwardly and enters the heat-pipe 4. The purpose of the steam-pipe 14 is to allow the excess of steam to pass off through the draft-pipe. Extending from the lower end of the water-tank is a water-pipe 15, which is provided with a three-way cock or with three cocks, each of which acts independently of the others. The Water is drawn from any source higher than the top of the water-tank and enters the pipe 15 and the tank, as indicated by the arrow 16, and when I wish the water to pass into the tank I open the two cocks 17 and 18 and close the cook 19. When I wish the hot water to pass into the tub 20, I close the cock 17 and open the cooks 18 and 19. When I Wish the cold water to enter the tub, I open the cooks 17 and 19 and close the cook 18, and when I want hot and cold water both to enter the tub I open all three cocks.

Ordinarily in all stove heaters whether the stove is an ordinary stove or a latrobe at least three-fourths of the heat passes up through the draft-flue with the smoke and cinders, and thus while we are attempting to heat our rooms, water, or other things we are absolutely permitting three-fourths of the heat to escape. One of the objects of my invention is to prevent this great waste of heat.

It will be observed by following the arrows that the heat is deflected by the plate 10 and goes upwardly inside of the heat-pipe 4 until it reaches the lid 5 and then it is returned and passes between the arms 9 and up through the draft-flue 8. Thus the heat is retained for a long time in thespace between the two pipes 8 and 4. The heat is conducted through the said pipe 4 into the water in the tank.

Sometimes I manufacture this heater by leaving off the arms 9 and the plate 10, and this form works quite well this way; but with this construction a considerable part of the heat passes up directly through the flue-pipe without having first been deflected into the space between the two pipes 8 and 4.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination of a stove 1, having a partly-open top; a heat-pipe 4, extending upwardly from, the opening in the top of said stove; a cap 5, fitting on the top of said pipe, and provided with a central perforation; a draft-pipe 8, secured in the center of said perforated cap 5, and passing down through the center of said heat-pipe, nearly to its lower end and up above said perforated cap; arms 9, secured to the lower end of said heat-pipe, extending downwardly; a plate 10, larger in diameter than the diameter of said draft-pipe, secured horizontally to the lower ends of said arms; a water-tank, provided with an inlet near its lower end, situated on the top of said stove and around said heat-pipe 4; a lid, fitting on the top of said Water-tank provided In testimony WhereOfIafliX my signature in With a manhole 12; a lid 13, removably sethe presence of two Witnesses. cured over said manhole; a steam-pipe 1 L,
